OBJECTIVES/HYPOTHESIS: To determine the 10-year incidence of hearing impairment (HI) and associated risk factors in the Beaver Dam Offspring Study (BOSS; 2004-present), a large middle-aged cohort followed for 10 years.
STUDY DESIGN: Prospective cohort study.
METHODS: Hearing thresholds were measured at baseline (2005-2008) and 5- (2010-2013) and 10-year (2015-2017) follow-up examinations. HI was defined as a pure-tone average >25 dB HL in either ear. BOSS participants free of HI at baseline with at least one follow-up examination (N = 2,065) were included. Potential risk factors evaluated included cardiovascular measures, health history, lifestyle factors, inflammatory markers, vitamins D and B12, lead, and cadmium.
RESULTS: Participants were 21 to 79 years (mean age = 47.9 years) at baseline. The 10-year cumulative HI incidence was 17.4% (95% confidence interval [CI]: 15.7-19.2) and was twice as likely in men (24.4%, 95% CI: 21.5-27.7) than in women (12.2%, 95% CI: 10.3-14.3). In a multivariable adjusted model, age (hazard ratio [HR] = 1.48, 95% CI: 1.38-1.59, per 5 years), male sex (HR = 2.47, 95% CI: 1.91-3.18), less than a college education (HR = 1.35, 95% CI: 1.02-1.79), body mass index (HR = 1.03, 95% CI: 1.01-1.05, per kg/m2 ), and higher cadmium levels (HR = 1.42, 95% CI: 1.05-1.92, quintile 5 vs. quintiles 1-4) were associated with the 10-year cumulative incidence of HI. There was no association between high lead levels, vitamins D or B12, and 10-year incidence of HI.
CONCLUSIONS: In addition to age and sex, obesity, education, and blood cadmium levels were associated with increased incidence of HI. These prospective results add to evidence that age-related HI is a multifactorial preventable disorder.
